Description
Using parm HASH=YES is not required for MICS as it's not an SMP installable product.
Solution
Although HASH=YES will work, it is acceptable to use:
//STEP1 EXEC PGM=GIMUNZIP,REGION=0M,PARM='HASH=NO'
**NOTE**
If the HASH=YES option is specified, then GIMUNZIP performs SHA-1 hash checking for the archive files.
